Answer:
Design. Modern headframes are built out of steel, concrete or a combination of both. Timber headframes are no longer used in industrialized countries, but are still used in developing nations
Answer:
The customs of JROTC demonstrates respect for the nation and the JROTC program by doing the following;
1) Standing at an attention position facing the Colors or the direction from which the music is heard and saluting whenever the National Anthem is playing
2) Obeying the rules and regulations and abiding by all JROTC customs, courtesies and protocols including the observance of the protocols regarding the use of phones, going through a doorway, manner of address and what to do when a higher rank, officer or dignitary enters the room.
Explanation:
Courtesy in the military is an expression of respect and or consideration for other persons or a notion
Excepted packaging refers to fiberboard boxes, sturdy wooden boxes, or steel crates that are designed to transport materials with extremely low levels of radioactivity.
<h3>What is
excepted packaging?</h3>
Excepted packaging can be defined as a type of box that is designed and developed for the transportation of materials with extremely low levels of radioactivity.
This ultimately implies that, a type of box which is strictly used for the transportation of materials with extremely low levels of radioactivity in order to prevent hazard.

The intensity w of the distributed load so that the average normal stress in the rod AB does not exceed 390 kPa are the 3 N/m.
<h3>What is a strain?</h3>
Strain is the quantity of deformation skilled via way of means of the frame withinside the path of pressure applied, divided via way of means of the preliminary dimensions of the frame. The following equation offers the relation for deformation in phrases of the duration of a solid: ϵ = δ l L.
- Assume that the common regular strain withinside the rod AB is the standards of failure.
- Calculate the withinside the rod AB the usage of the subsequent formula: sigma AB = T A A AB sigma AB Here, is the common regular strain withinside the rod AB, A AB is the cross-sectional region rod AB
- 390 kPa*( 10^ 3N/m^ 2 1 kPa ) fOr sigma AB and Substitute
- 10 mm^ 2 *( 10^ -6 m^ 2 1 mm^ 2 ) for A AB:i equation. the above
- 390/10 ^ 3| = T_/(10|10 ^ - 6|) T_ = 3N.
- Determine the importance of w through thinking about the moments approximately factor C . sum M c =zero
- T_ * (L) + [(1/2)(6)(w)](L/three) = zero (2)
- Substitute three N for T_ and six m for L withinside the equation (three).
- - 3(6) + [(1/2)(6)(w)](6/3) = zero w = 3N / m
